Currently we have a lot of duplicated checks of if (start == 0 && fs_info->sectorsize == PAGE_SIZE) cow_file_range_inline(); Instead of duplicating this check everywhere, consolidate all of the inline extent logic into a helper which documents all of the checks and then use that helper inside of cow_file_range_inline(). With this we can clean up all of the calls to either unconditionally call cow_file_range_inline(), or at least reduce the checks we're doing before we call cow_file_range_inline(); Reviewed-by: Goldwyn Rodrigues <rgoldwyn@suse.com> Signed-off-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: David Sterba <dsterba@suse.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
